Can't have it that way. A rooster of any breed will mate a hen of any other breed. They aren't picky. Now, if you want them to run together, then separate out a rooster and certain hens for several weeks so you are sure it's that particular rooster who is the sire of the chicks, you can do that. Some folks let their flocks run together all winter, then separate out certain breeds into pens for hatching out chicks of that breed in the spring/summer.
ETA: I love my mixed laying flock, led by my Delaware rooster. I currently have only two Delaware hens so I know their eggs are pure, but of course, if I incubate any others in that flock, they'd be Dellie crosses so I rarely do that.
